Solar energy is the key area of business at Austria Solar: Serviceplan developed a surprising and attention-grabbing annual report for the Vienna-based organisation that not only puts solar energy to paper, but also positions Austria Solar as a consistently innovative industry organisation in the Austrian solar sector. Thanks to a special printing process, the content of the individual pages only becomes visible when sunlight falls on it.The report was sent at the beginning of the year to the members of the Austrian solar organisation in addition to various representatives from business and politics.
